HEATING Arranamus.

Application med November 29, 1926. Serial No. 151,581.

My invention relates to a heating apparatus.L

The object of my invention is to `provide a unit heater, which will withdraw the cool air from the floor and discharge the air in heated condition at a very considerable elevation above the Hoor.

lt is a further object of my invention to provide a heater, in which the fan is closely adjacent to the radiator, so that the air can be driven through the radiator with the maximum velocity and dispersion. A llt is afurther object of my invention to provide the radiator to one side of the incoming air passageway, so that the maximum capacity of that passage-way may be utilized.

lt is a further object of my invention to so locate the radiator on the outside of the unit that the heat therefrom may be radiated in aY zone about the passage of the air..

lt is a further object of my invention to provide a very narrow circulation box, which serves as a support for the radiator and fan, as well as a draft passageway and is of such narrow floor dimensions at the base that it will take up the minimum of floor space, while the maximum dimensions of the apparatus are located at thetop thereof above the occupants of the room and the contents thereof.

lli/ly invention produces high heat eciency of direct radiation with only one-tenth the weight of direct radiation and one-fourth the space of equivalent direct radiation, and involves much less time to install.

Referring to the drawings:

Figure l is a side elevation thereof;

Figure 2 is a front elevation thereof;

Figure 3 is a section on the line 3-3 of Figure 1, looking in the direction of the arrows;

Figure 4c is a detail of the screen clip;

Figure 5 is a detail of the screen;

Figure 6 is a top plan view of the unit;

Figure 7 is a section on the line TI-7 of Figure 2. l

Referring to the drawings in detail, 1--1 designate uprights joined at the Hoor by transverse angleirons 2, thus forming a rectangular frame work which is of relatively great height and narrow transverse dimension. Preferably, the side plates 3 are not as wide as the front and back plates 4c. The side and front plates are spaced above the door as indicated, allowing an air entrance openture shaft of which is carried a faul() turn` ing within this plate, which is struck up to form a fan casing extending from the periphery of the fan to the outer wall of the casing 6 and the edge of the radiator 11. This radiator is attached in front of the fan closely adjacent to it on the outside of the housing 6. It will be noted that it extends beyond the general dimensions of the supporting cabinet and the cabinet 6. It is adapted to radi- Y ate heat laterally as well as to distribute h'at due to the forced draft of the fan passing therethrough at high velocity. The radiator is preferablyof copper and brass consisting of that type known as Aerolin, which is a series of nonferrous pipes each having mounted thereon a spiral, fluted fin.

On the front of the radiator casing is mounted in a frame 12 a coarse screen 13, which serves to protect the radiator and distribute the outgoing heated air.

The exact arrangement of this radiator will be seen in Figure 7.

14 refers to the tubes having the fluted fins 15. These tubes are mounted in a transverse supporting plate "16 at either end, which, in turn, is supported in a tubular angle supporting header 17. This header is supported on a cast brass tapping header hub 18 that is threaded at 19. This hub is provided with a key supporting tapping hub plate 20 mounted upon the casing 21.

The casing 21 is surrounded by an outside box 11a forming the radiator supporting box.

lt will be understood that l desire to comprehend within my invention such modifica` tions as may be necessary to adapt it to varying conditions and uses. V

Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent, is 1'- 1. lin combination, a relatively high and narrow air circulation passageway open at the bottom for the inlet of the air and open at its side at the top thereof for the exit of air, a fan suspended in said opening, and a radiator mounted on the outside of said passaoeway directly in front of said fan closely adjacent the radiator and parallel with itstace, whereby the air is driven through the radiatorat high velocity.

j pended on the side of the last 2. In combination, al circulation assageway adapted to take air from the oor and discharge it at the top above the floor, said passageway conslsting ofan air delivery unit and a `fan housing and radiator supporting unit, a radiator and radiator casing susmentioned unit adjacent an openinfr therein, and a detachably supported fan housing plate carrying a,

adjacent said opening, a-high speed fan suspended in said opening adjacent the radiator, said radiator consisting of a plurality of horizontally disposed pipes having spiral fins thereon, a header for said pipes at either side thereof, and a casing enclosing said header.

4. In combination, a relatively narrow and tall air circulation passageway open at its bottom adjacent the floor and open on the side adjacent the top, a radiator suspended on the outside/of this air circulation chamber adjacent said opening, a high speed fan suspended in said opening adjacent the radiator, said radiator consisting of a plurality of hori zontally disposed pipes having spiral fins thereon, a header for said-pipes at either side thereof, and a casing enclosing said header, and a spacedscreen mounted over the face of said radiator to protect it and disperse the loutgoing heated air.
